These units do exactly what I needed to know if anyone has entered my property

I ordered an extra transmitter along with the DI2000S-AG Driveway Informer Kit. I already have the transmitter from the kit set up near the end of our long driveway to alert us to people or vehicles approaching the house from the street. Since we don't have an actual doorbell, I installed this second transmitter on our porch so that we know when anyone has reached our front door.

As mentioned in my review of the Driveway Informer Kit, the two screws for the mounting bracket and those for securing the halves of the transmitter together were very tight and difficult to remove. After getting them out, I applied some silicone grease to the screw threads, which made loosening and tightening the screws much easier and facilitating future battery replacements.

Only two screws are used to hold the case halves together. I would prefer that four screws be used for this purpose so that the silicone gasket between the case halves will be compressed evenly all around its perimeter, thus ensuring a tight seal.

I would like to see this product offered in a few different colors in addition to the satin green: Tan, brown, black, and even a camo pattern could improve the unit's concealment in different locations and environments.

Overall, this is a very good US-made product and highly recommended should you need one or more additional transmitters.

Very helpful. They helped me determine which product would be best for my application and it was different than what I initially contacted them for. It has since been installed and works fantastic. Highly recommend them for their products and customer service.

We have had our driveway monitor for 20 years - and just recently had a problem with the transmitter (only because one of the screws stripped and couldn't make the seal tight enough and water penetrated the circuit board inside). Can't live without this product when you live out in the country with a very long driveway!! Great product and reasonable priced!

This driveway announcer works wonderfully, the order arrived timely and the second transmitter we placed in the back patio warns us of any critters in that area.
